Storm sash



UNITED STATES PATENT OFFICE CECIL F. CHARLTON, 0F BIRMINGHAM, MICHIGAN STORM sAsn `Application filed January 14, 1929. Serial No. 332,467.

This invention relates to sash constructions and more particularly to an improved storm sasl applicable to all standard makes of steel sas One of the objects of this invention is to provide a storm sash whose construction and design permits the same to be readily attached to the standard makes of metal or steel sash and more particularly to the outer side thereof.

Another object of this invention is to provide an improved and novel form of sash frame which may be readily and veconomically manufactured and which will be durable and rigid.

Various other objects and advantages result from the combination, construction and arrangement7 of the several parts of the device, all of which will be made more apparent as this description proceeds, especially when considered in connection with the accompanying drawings wherein: v

-Figure 1 is an elevational view of a standard metal sash withmy improved storm sash associated therewith;

Figure 2 is an enlarged vertical sectional -view taken substantially on the plane indiyau cated by yline 2--2 in Figure l;

Figure 3 is an enlarged vertical sectional view taken substantially on the plane indi- ,y t

" required number of these tongues 24 may be bf the,

cated by line 3-3 in Figure 1, and,

Figure 4 is a fragmentary detail perspective view of a portion of the storm sash frame showing the glass holding clips.

Referring now more particularly to the drawings wherein like reference characters indicate like parts, it will bev noted that there is illustrated a frame 10 defining the window opening which is closed by the sash indicated generally by the reference character 11. Both the frame 10 and the steel sash 11 are of standard cross section, the anges 12 and 13 of the-steel sash engaging respectively the flanges 14 and 15 ofthe frame. The reference character 16 indicates the glass of the steel sash and in Figure 1 the reference character 17 indicates the usual muntin bars.

In accordance `with the present invention I propose mounting and attaching the storm sash directly to the frame of the steel sash erally by the reference character 17 and comprisingy top and bottom frame members 18 and 19 respectively and side frame members 20. The ends of the frame members 18, 19 and 20 are mitered and are preferably se-l cured together by welding. v

As seen from Figures 2 and 3 the storm sash frame is pressed, rolled, or otherwise constructed of relatively thin sheet metal, and in order to provide for the requisite rigidity and for other purposes which will also appear, each frame member is formed with an angularly extending rib`21 provided by bending the metal of the frame back upon itself. As seen, the rib 21 of the frame ex. tends longitudinally of each of the frame members 18, 19 and 20 and substantially centrally thereof and thus divides the frame member into an outwardly extending flange 22 and an inwardly extending flange 23.

At spaced points throughout the frame 'the metal at one side of the rib 21 is cut to provide tongues 24 which may be bent from the plane of the rib in the manner more clearly suggested in Figure 4, and thus constitute.

provided.

The outwardly extending flange 22 storm sash frame is apertuged at spaced points and the'steel sash frame is provided with threaded apertures for receiving securing screws 26.

A layer of felt or other substantially similar material 27 is preferably interposed between the storm sash frame and the inner face of the steel sash frame and the securing elements 26 are obviously passed therethrough.

In order to facilitate the application of the storm sash to the steel sash I provide a locating means which may conveniently com- 'prise a pin 28 carried by a bracket 29 attachedtothe lower frame member 19 of the storm sash. This pin is adapted to engage an aperture 30 formedy in a plate 31 secured to the lower edge ofthe steel sash frame.-

Thus the storm sash may be located by engaging pin 28 with aperture 30, whereupon it can be moved into engagement with the frame of the steel sash and securing elements 26 put into position.

v The structure is preferably provided with a handle 32 secured to one of the vertical frame members of the storm sash.

From the herein described construction many advantages are realized and in addi tion the structure is simple, durable and may be economically manufactured and installed with facility. While an embodiment of the invention has been described and illustrated f j ,Y herein somewhat in detail, itwill be apparent to those skilled in this art that various changes in many of the essential and all .of the non-essential details of construction may be resorted to without departing from the spirit and scope of this invention and to this end reservation is made to make such-changes as may come within the purview of the accompanying claims.

What I claim as my invention is:

l. The combination with a metal sash, of a storm sash having a frame formed of sheet metal shaped to provide in cross section an angular rib with inwardly and outwardly extending peripheral flanges, means for securing a glass sheet against said inwardly extending flange and means passing through' said outwardly extending flange for securing said storm sash to said metal sash.

2. The combination with a metal sash of standard section having inner and outer flanges, of a storm sash formed of sheet metal shaped to provide an angular strengthening rib and inwardly and outwardly extending peripheral flanges, means for securing a glass sheet against said inwardly extending flange' and means extending through the outwardly extending flange of said storm sash and the outer flange of said metal sash 'for securing said storm sash to said metal sash.

In testimony whereof l ax my signature.
